To all LU/wm z5-may concern.'

Be it known that I, IVILLIAM ADAMS, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inChandeliers, of which the following is a specification.

My invent-ion relates to that class of chandeliers in which the lightingunit and its associated ray-directing means are adapted to be turned fordirect or indirect lighting, that is, to direct the light eitherdownward or upward.

My invention is particularly applicable to that type of chandeliershaving a single lighting source, or a group thereof so closelyjuxtaposed as to be in effect a unit, and which may, therefore, betermed a unit type of chandelier in general contradistinction to acluster type, such, for example, as those having a plurality ofindependent arms or branches. In chandeliers of this type in which thebody, structure carrying the lighting unit and its associated shade orray-directing means is pivotally -suspended by hanger-arms adaptingthese parts to be reversed, a somewhat simple problem is presented,where only two oppositely located hanger-arms are employed, for the bodystructure may in such case be swung up or down between said arms. Butwhere it is desirable that more than two hanger-arms be employed, as,for eXample,`for the sake of proportional design in heavy Xtures, somemeans must be devised for getting such additional arms out of the way,in order to permit the swinging movement of the body structure betweenthe two opposite arms from which it is pivotallv suspended.

The object of my invention is to provide for this result, and to thisend my invention consists in the novel constructions and arrangementswhich I shall now fully describe by reference to the accompanyingdrawings, in which Figure 1 is an elevation of my chandelier. Fig. 2 isa top plan view taken from below the canopy. Fig. 3 is a sectionaldetail, enlarged, showing the connection of three of the hanger armswith the poly-branch hanger-head. Fig. 4 is a similar detail, showingthe pivotal connection at the upper end of the fourth hanger arm. Fig. 5is a detail section showing the pivotal connection of the lower ends oftwo of the hanger arms with the body shell. Fig. 6 is a detail seo`-tion showing the detachable connection of the lower ends of the othertwo hanger arms.

1 is the canopy and 2 is the stem of the chandelier. To the lower end ofthis stem is fitted the poly-branch hanger head 3. In its bestconstruction it has four symmetrical and equidistant branches,designated by 4, 5, 6 and 7, which carry the hanger arms 8, 9, 10 and 1lrespectively. Three of these branches 4, 5 and 6 are connected with andcarry their hanger arms 8, 9, and 10 respectively hy some suitable'formof permanent attachment. That shown in Fig. 3 is a good construction. Itconsists of an ornamental knob 12 screwed to the end of the branch. Inthe t-op of this knob is screwed an ornament 13, and into its lower faceis screwed the upper end of the hanger arm. The fourth branch 7 carriesits hanger arm 11 by a pivotal connection of some suitable characterwhich permits said hanger arm to swing laterally. This connection isshown in Fig. 4 in which A12l is an ornamental knob similar in generalrespects to the knobs 12 and carrying the ornament 13 and the hanger arm11 in the same manner. But said knob 12 has a reduced port-ion 14 whichis rotatably mounted or journaled in the branch 7 and is held therein bya stud 15 in the branch entering a circumferential groove 16 in thereduced portion 14.

The body-shell is of suitable, character. It is here shown as comprisinga top band 17, frame arms 18 and a bottom holder 19. This Ashell carriesthe lighting unit or lamp 20, and the ray-directing means or shade 21,in the accepted manner. The shell is pivotallv connected with the lowerextremities of two opposing hanger arms, namely 8 and 10. The pivotalconnection is best made as shown in Fig. 5. The lower ends of the hangerarms S and 10 screw into fittings 22` each of which at its inner end istapped with a short nipple 23. The body band 17 is pivoted on thisnipple and is held against the fitting by a nut 24 on the inner end ofthe nipple. The bodv shell is detachably connected with the other twohanger arms 11 and 9 bv some suitable connection. That shown in Fig. 6is deemed the best. The lower ends of the hanger arms 11 and 9 arescrewed into iittings 25. the inner ends of which bear against the bodyband 17. On the inside of the band. which is quite thin, is secured areinforcing piece 26 thick enough for an internal thread to receive thelighting.

threaded end of a screw-pin 27 which passes through the fitting 25 andthus holds said fitting to the band. The head of the pin 27 isornamental to resemble the ornament of the other fittings 22, so thatthe design is uniform.

The operation is as follows: Suppose the body-shell be in the positionshown in full lines in Fig. l in which the light rays are directedupward for indirect lighting. In this position the body-shell issuspended by all four hanger arms, and is locked in this positionagainst swinging movement, because, though its pivotal centers are free,the hanger arms 9 and 11 are in its path of movement and moreover aresecured to it. Now, in order to reverse the light, both hanger arms 9and 11, are released from the body shell Vband 17, by unscrewing thepins 27. Then the hanger arm 11 is swung sidewise on its pivotalconnection at its upper end, to a position out of the way, as isindicated in dot-ted lines in Fig. l. Thereupon the body shell with itslight unit and raydirecting means is swung upward away from the releasedbut still positioned hanger arm 9, and betweenA the pivot suspendinghanger arms 8 and 10 to a reversed position as shown by the dot-tedlines in Fig. 1, so that the parts are then in position for direct Inthis position the hanger arm 9'acts as a stop to limit the reversal ofthe parts, forthe body shell will at said limit come in contact with it.Finally, to lock the parts in this reversed position, the hanger arm 11is swung sidewise back to its normal place, and then both hanger arms 9and ll are again secured to the body band 17 by screwing in the pins 27.The screw pin holes in the body band are, of course, reversed, for theband is reversed, but as their location is symmetrical, the ping 27readily engage them.
